Abstract: HAMMER BANK MOVE CONTROL SYSTEM     ABSTRACT OF THE DISCLOSURE         A hammer bank system for use in a high speed impact printer includes a movable hammer bank in which the hammer spacing is twice the character spacing.  A hammer bank controller is used to move the entire hammer bank between two selected hammer bank positions.  In one hammer bank position, the hammers are aligned with odd character positions and in the other hammer bank position, the hammers are aligned with the even character positions.  The hammer bank controller in response to a move command signal from the printer logic section drives the hammer bank (in a velocity mode) from one of its positions to the other first at an increasing velocity, followed by a constant velocity, until the bank is at a selected distance from the desired position, at which time the hammer bank velocity is decreased to zero and the hammer bank is substantially at the desired position.  The controller switches to a position mode in which a position signal is used in a position servo loop to lock the hammer bank at the desired position.  In normal operation when the bank is switched to the position mode, a move complete signal is fed back to the printer logic section to terminate the move command signal.          Positioning initialization circuitry is also included to automatically drive the hammer bank to one of its desired positions.

Abstract: Abstract of Disclosure An artificial tooth for use in a denture compris-ing a base portion, an occlusal portion, and an intermediate portion sandwiched between and secured to the base portion and occlusal portion, the intermediate portion being re-silient to permit the occlusal portion yieldably to move relative to the base portion.  The intermediate portion is disposed generally at equal vertical distances from the occlusal surface of the occlusal portion and the ridge lap surface of the base portion.  Two connecting members, spaced apart in the mesial-distal direction, are provided for limiting the movement of the occlusal portion relative to the base portion.  Such members are rigidly connected to the occlusal portion and loosely pivotally connected to the base portion.  The loose pivotal connection permits the occlusal portion to move from its normal position toward the base por-tion even by tipping movement. The tooth may also include vertically extending tabs or projections connected to the occlusal portion or the base portion or both to limit the movement of the occlusal portion.  The projections may be so situated between the occlusal and base portions to pre-vent excessive tilting of the occlusal portion, a pinching of the resilient portion and rotation of the occlusal por-tion with respect to the base portion.

Abstract: Abstract of the Disclosure A method of treating raw materials containing components of metals of the group IVb of the Periodic Table, which comprises heat-treating a raw material of a component of a metal of the group IVb of the Peri-odic Table containing coloring poisonous metal compo-nents such as Mn, V and Cr components in the presence of a flux composed mainly of an alkali metal nitrate or an alkali metal peroxide which is a thermal decom-position product of the alkali metal nitrate in an amount 2 to 5 times the amount of the raw material on the weight basic in a non-reducing atmosphere to thereby effect fluxing reaction, and subjecting the resulting fluxing reaction product to a leaching treatment of at least one stage in an aqueous medium to separate the fluxing reaction product into said coloring metal com-ponents and a concentrate of the component of the group IVb of the Periodic Table which is acid-soluble and substantially free of said coloring poisomous metal conponents.  In practising this treating method, if a residue left after the above leaching step is incorpo-rated into a mixture of the raw material and the flux, the composition is granulated and the granulated com-position is heat-treated, the fluxing reaction of the raw material can be accomplished while keeping the granulated composition in the substantially non-sticky granular state throughout the fluxing heat treatment.

Abstract: Abstract A waveguide structure composed of circular waveguide cavities resonant in the TEo11 mode is capable of realizing the most general bandpass filter characteristics with signifi-cant decreases in filter loss and gain slope.  In addition to the commonly used Tchebychev and Butterworth functions, the structure can realize general transfer functions, including the elliptic function.  In its simplest form, the structure is composed of four cylindrical cavities which form a building block for more complex filters.  The first and second cavities and the third and fourth cavities each have their side walls in contact and their end walls in common planes.  The third and fourth cavities are superposed to the first and second cavities with their adjacent end walls in a common plane, but the second and third cavities are offset so that they overlap at one-half diameters.  The first and second cavities are coupled by means of a centrally located side wall slot, as are the third and fourth cavities.  Coupling between the second and third cavities is by means of a radial slot in their adjacent end walls, and the first and fourth cavities are similarly coupled.  However, to generate the most general class of coupled transfer functions, the sign of the coupling between the first and fourth cavities and between the second and third cavities must be different.  This is accomplished by the offset of the second and third cavities.
